Gnuplot in JSP ----- URGENT

Hi
I am trying to create a graph using "GNUPLOT". I use the Runtime.exec(cmd) to execute the gnuplot where cmd = gnuplot temp_cmdFile and i am trying to run this through a JSP. The problem i encounter is the temp_cmdfile is created by the JSP but the output file is not created. the gnuplot command has a statement which says set output filename but this filename is not being created.

Mozilla n' Firefox shows HTML source for JSP(URGENT!!)

Hi all,
I have made a web application with JSPs. It seems to work fine with IE. However, with Mozilla and Firefox, it displays the HTML source generated by JSP instead of actually showing the HTML page for that source.
I'm stumped because I haven't found any other msgs on forums with someone experiencing the same problem. Any help would be appreciated. I need to fix this urgently.
Thanks

Download a text file from JSP (Urgent Please!)

Hi,
I have a issue with this JSP, I need to download a txt file from my webserver to the pc client, the page shows the dialg box but appear the filename (list.jsp) of my jsp instead of the txt file.
If I click the save buton save the list.jsp page; if I click in the open buton, then appear again the dialg box and now appear the url (download.jsp?filename=...) and if I click in the save button now I can save my txt file in the local pc.!!!!
Any ideas ??
list.jsp --> is the jsp from the download.jsp is run.
download.jsp
<%@ page import="java.io.*,javax.servlet.*,java.util.* "%><% String filename = request.getParameter("filename");
response.setContentType("application/download");
String value = "attachment; filename=\"" + filename + "\";" ;
response.setHeader("Content-Disposition",value);
int iRead;
FileInputStream stream = null;
try {
File f = new File("C://test//" + filename);
stream = new FileInputStream(f);
while ((iRead = stream.read()) != -1) {
out.write(iRead);
out.flush();
finally {
if (stream != null) {
stream.close();
%>

Maybe try no quotes around the content disposition header?
Also, I'm not sure that application/download would be the best content type, maybe "application/octet-stream" instead. You should also probably explicitly set the Content-Length header to the file size.

Implementing session timeout in JSP - - Urgent help !

Hi
I have a requirement where I need to write a session timeout functionality in a JSP such that the page is redirected to a different page if there is no activity for 5 min.
I tried the following :
1.On the onload of my JSP, i created a new session from the current request using the following code snippet :
          HttpSession pSession = request.getSession(true);
          pSession.setAttribute("loggedin","true");
          pSession.setMaxInactiveInterval(10);
2. Then on any action performed on the JSP, i called the collowing JS function before invoking the server side code.
/** function to check the user session **/
function fnChkSession()
     alert('Inside check session');
     <%
          try
               System.out.println("The value of the session var loggedin : "+pSession.getAttribute("loggedin").toString());
               System.out.println(" getMaxInactiveInterval() value is : "+pSession.getMaxInactiveInterval());
          catch (Exception e)
               System.out.println("** Inside the fnChkSession exception catch block **");
          if (pSession.getValue("loggedin") == null)
     %>
          alert('Session has expired');
          document.forms[0].submit();
     <% } %>
But when I execute this code ,even after 10 secs my session seems to be alive.I can retrieve the session attribute after 10s.
I also tried setting the session-timeout value in the web.xml. It didnt work.
Can anyone pls help me on how to proceed further on this.
Thanks

You are confusing java with javascript.
These two things are not the same.
The lifecycle goes something like this
1 - Request is made to server
2 - Java/JSP runs java code, produces HTML page
3 - java stops running
4 - html is sent to browser, and javascript starts running.
You cannot call java code from browser events (such as onload, onclick, onchange...) The only way to run java code again is to submit a request (normally by submitting a form, or clicking a link. )
If you want a javascript solution, in IE, use the window.setTimeout() method to execute some javascript code after a certain period of time.
A more generic approach would be to use the refresh header. Set the timeout for the refresh header to be 300 seconds. If the user stays on the same page for more than 5 minutes, it will redirect to the new page.
Hope this helps,

How to build dynamic menus using JSP==Urgent==Please Help me

I have exhausted searching on internet to find a book

java to do this without DHTML or atleast sample code.
can somebody help me in this regard.
Thanks

I would be greatful if you could send me the sample code.

Help in Jsp- Urgent

Getting option value in jsp: Urgent help will be appreciated

Hello All,
I am working on JSP. I will grade myself as beginner in JSP.
I am trying to solve since last 2 days, I just want to display the value of option tag, and not able to get it.
<table>
<tr>
<td>
<html:select name="ActionForm" property="overage">
<%
int i;
int[] arr1=new int[200];
for (i=0;i<=100;i=i+10)
arr1=i;
%>
<html:option value="/<%=i%>/"><%= arr1%></html:option>
<%}%>
</html:select>
</td>
</tr>
</table>
Please, ignore the syntactical error.
Now in above code I want to know what is being put up as value of option tag. By value I mean , I want see <html:option ]value="/<%=i%>/> . (Data marked in bold)
Your help will be appreciated. I tried couple of things such as getParameter(), get Attribute(), getOverage(). Some of it gave me value as "//", it skips the i variable.
I want to see what is being put up in value for every iteration of loop

Yeah I know. But thnx for the response.
I also got that error solved. you know what it was because of those bckslashes. i wrote it,
<html:option value="<%=i%>"><%=arr%> instead of
<html:option value="/<%=i%>/"><%=arr[i]%>
and that worked perfectly. I wish I could have known this before. It would have saved me lot of time.

Login page in jsp-urgent

hello to all,
i am using tomcat 4.1.24,i have created a login page where i am forwarding the username and password to a jsp file where it process the validation by instantiating the bean and sets the property,but when it (Process.jsp)calls a method in bean validate() the main problem i am facing is whatever userid and password i type it is just taking the success.jsp page which is added in Process.jsp file and displaying the contents and i don't think it matches with the database records by instantiating the bean.could anybody tell me where i have gonw wrong.i have attached code below and i have used Msaccess to retrieve records.please help me.
Login.jsp
<html>
<head>
<title>Login page</title>
</head>
<body>
<br>
<p><h3><center>Please enter your name and password</center></h3></p>
<br>

<form action="Process.jsp" method="post">

<center><input type="text" name="username"></center>
<center>Password</center>
<center><input type="password" name="password"></center>
<center><input type="submit" name="submit" value="login">
</center>
</form>

Process.jsp
<%@ page import="java.util.*" %>
<jsp:useBean id="idHandler" class="foo.Login" scope="request">
<jsp:setProperty name="idHandler" property="*"/>
</jsp:useBean>
<%
if (idHandler.validate()) {
%>
<jsp:forward page="success.jsp"/>
<%
else {
%>
<jsp:forward page="retry.jsp"/>
<%
%>
Login.java
package foo;
import java.sql.*;
public class Login
private String username="";
private String password="";
public Login()
public void setUsername(String username)
this.username=username;
public void setPassword(String password)
this.password=password;
public boolean validate()
String query="select * from USER";
String Dbusername="";
String Dbpassword="";
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:Visualcaccess");
Statement st=con.createStatement();
ResultSet rs=st.executeQuery(query);
while(rs.next())
Dbusername=rs.getString(1);
Dbpassword=rs.getString(2);
if((username.equals(Dbusername)) && (password.equals(Dbpassword)))
break;
return true;
}catch(Exception e)
e.printStackTrace();
return false;

The reason your program is always forwarding to success.jsp is because of a logic error in Login.validate();
After cycling through all the results in the resultset your method returns true regardless of whether the user was found or not.
Instead try getting a count of the users in the database that have the given user name and password.
Here's an example: (replace "USERNAME" and "PASSWORD" with the name's of the columns in you database)
public boolean validate()
String query="select count(USERNAME) as usercount from USER where USERNAME='"+username+"' and PASSWORD='"+password+"'";
try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     Connection con=DriverManager.getConnection("jdbc:odbc:Visualcaccess");
     Statement st=con.createStatement();
     ResultSet rs=st.executeQuery(query);
     rs.first();
     if (rs.getInt("usercount") > 0)
          //There is an entry in the USER table with the given username and password
          return true;
     else
          //There isn't an entry in the USER table with the given username and password
          return false;
catch(Exception e)
     e.printStackTrace();
     return false;

JSP- Servlet- Same JSP - Urgent HELP!

I have a scenario as follows:
The JSP is a Login JSP which forwards the request to the Servlet to validate the Login info from the HTML. This I do by submitting the JSP page to itself & in the beginning checking if the Submit button was clicked, if yes, then I extract all the form elements by request.getPArameter(element name) & set in on the request using request.setAttribute() methods! The servlet uses the values by doing a request.getAttribute() & say, a validate User failure, the servlet ahs tor edirect user to the same Login.jsp page, but the second time, the "Submit" button value is still true, since the servlet forwards the same request, response & this ends in an infinite loop, of JSP calling Servlet, the User validation fails & the Servlets calls the JSp again, and so on.
How do I reset the HTML form element values in the JSP before forwarding to the Servlet? is there a request.setParameter() method? Or is there a way for the servlet to forward a new request & response to the same JSP?
Thanks in advance.

if the user is invalid.. redirect them to the error page and in the error page pu this javascript... It will refresh the page so the loop will not happen.
<script language="JavaScript">
var sec2count = "2"
var redirectpage = "Login.jsp"
function countdown() {
if (sec2count == "0") {
document.location = redirectpage
else {
sec2count = sec2count - 1
document.form1234.counter.value = sec2count
setTimeout("countdown()", 1000)
countdown()
</script>
